ALSA: hda - Add a generic reboot_notify
commit 871b9066027702e6e6589da0e1edd3b7dede7205 upstream.
Make codec enter D3 before rebooting or poweroff can fix the noise
issue on some laptops. And in theory it is harmless for all codecs
to enter D3 before rebooting or poweroff, let us add a generic
reboot_notify, then realtek and conexant drivers can call this
function.
